Why does CDC recommend 60 days of antibiotics?
Anthrax spores grow like plant seeds. If you plant seeds and give them sun and water, they will grow into plants. If you give anthrax spores the right environment, such as the human body, they can grow into the harmful form of the bacteria that can cause anthrax disease. It takes anthrax spores an average of 7 days to grow into the harmful form of the bacteria, but it can take longer. For this reason, CDC recommends preventive antibiotics for the full 60 days.
